Title
(EN) DIRECT MOUNTING OF FILTERS OR OTHER OPTICAL COMPONENTS TO OPTICAL DETECTORS USING FLEXURES
(FR) MONTAGE DIRECT DE FILTRES OU D'AUTRES COMPOSANTS OPTIQUES SUR DES DÉTECTEURS OPTIQUES À L'AIDE DE FLEXIONS
Abstract
(EN)
An apparatus includes an optical detector (102) configured to detect at least a portion of incoming radiation (104). The apparatus also includes an optical component (118) configured to provide at least the portion of the incoming radiation to the optical detector. The apparatus further includes at least one flexure (122) that mounts the optical component to the optical detector. Each flexure is configured to deform in response to expansion or contraction of at least one of the optical component and the optical detector. Each flexure may include a side surface (204) that is flexible in a first dimension and rigid in second and third dimensions, where the dimensions are orthogonal to each other. The optical component may include at least one of a filter, a lens, a polarizer, an aperture, and a cover.
(FR)
L'invention concerne un appareil comprenant un détecteur optique (102) conçu pour détecter au moins une partie d'un rayonnement entrant (104). L'appareil comprend également un composant optique (118) conçu pour fournir au moins la partie du rayonnement entrant au détecteur optique. L'appareil comprend en outre au moins une flexion (122) qui monte le composant optique sur le détecteur optique. Chaque flexion est conçue pour se déformer en réponse à l'expansion ou à la contraction du composant optique et/ou du détecteur optique. Chaque flexion peut comprendre une surface latérale (204) qui est flexible dans une première dimension et rigide dans de deuxième et troisième dimensions, les dimensions étant orthogonales entre elles. Le composant optique peut comprendre au moins un élément parmi un filtre, une lentille, un polariseur, une ouverture et un couvercle.
